Mr. Miker hastened to summon all his men, who lived near the quarries, and by eight o'clock they were on the deck of the gundalow. But it was no small undertaking to remove the derrick, for the mast was a very heavy spar, and was stepped in the bottom of the scow. The rigging and the long arm were taken from it, and then one of the movable derricks used in the quarries was brought on deck, and guyed up for work. With the aid of this machinery the mast was taken out, and deposited on the shore. The mast-hole was covered with a tight scuttle made for the purpose, and the gundalow was adapted to the business for which she was to be used in the expedition to Sandy Point. By this time it was nine o'clock, and the moon was just beginning to cast its silvery light upon the still waters of the little lake. Captain Dornwood promised to return the scow to the quarries before morning; but Mr. Miker said he should not use her for a week, and the captain could keep her as long as he wished. "We shall want a lot of blocks, planks, and timbers, but we have plenty of them on the school grounds, though we shall have to lug them a considerable distance to put them on board of the gundalow," said Captain Dornwood, as he was about to step into the boat. "Hold on then, Dory! I have everything you can possibly want in that line," interposed Mr. Miker. "The students have saved my men a vast deal of hard work in towing the gundalow, and they will be glad to put all the lumber you need on board of the scow." "That we will!" exclaimed several of the men in the same breath. "I don't want to give you and your men, who have been at work all day, any unnecessary trouble," added Dory. "No trouble at all!" protested the men, as they began to put the timbers on board. Dory was very grateful to them, and pointed out the kind of stuff he wanted, including a large pile of rollers used in moving heavy blocks of stone. In half an hour the gundalow was loaded with the materials Dory had indicated. In the little time at his disposal, the energetic leader of the enterprise had made a list of the material he was likely to require. He had been at work, while the men were loading the blocks and planks, with his pencil and paper, and had thought of several things that were of prime importance. "I am very much obliged to you, Mr. Miker, and I shall be still more so, if you will lend us eight jack-screws, for we have not enough of them at the shops," continued Dory. "Are you going to move a meeting-house, Dory?" asked the quarryman, laughing. "We are going to do something of that sort," replied the leader of the enterprise. "But I don't let on just yet."
